摘要: In April 1996 and 1998, the concentrations of polychlorinated dibenzo-p-dioxins (PCDD) dibenzofurans (PCDF) were determined in 40 herbage samples collected neighborhood a hazardous waste incinerator (HWI) under construction Constanti (Catalonia, Spain). 2000, 20 months after HWI began operating, again at same sampling points which had been taken previous surveys. PCDD/F ranged between 0.13 0.65 ng I-TEQ/kg (dry matter), with median mean values 0.29 0.32 respectively. The results compared those obtained (median, 0.53 I-TEQ/kg; mean, 0.61 I-TEQ/kg) 1998 0.23 0.31 While period 1996-1998 significant decrease (49%, P 0.05) was found PCDD/Fs. analysis suggests two potential hypotheses: either emissions PCDD/Fs from are not negligible, or current other sources near remained similar levels to reached 1998. Anyhow, an exhaustive evaluation present data shows absence notable contamination by area its direct influence. It seems also probable that decline atmospheric due emission this is currently stopped.
